Displays a map of what you point your device at twice using triangulation.

You move between A, and B locations and it will calculate C based upon the angles from your compass.

You should first save the magnetic declination for the area you are using, or you could try calibrating to find out the declination.

Will triangulate based upon your compass and GPS coordinates.

Compute distance between any A and B points.

Note: This program will only bring up a map as accurate as your GPS and compass are. Move your device in a figure 8 pattern to get a more accurate azimuth before you hit 'A' and 'B'.

The declination or magnetic deviation has been set to 13 by default, which is the Las Vegas, Nevada area. Consult an aviation map, Google, or calibrate to find the declination for your area.

To calibrate, go near an object which you can see from a distance south. Hit 'A', then go south a ways and hit 'calibrate' under the 'Adj' menu. You will see a number in feet. Move until it reads '0'. Point your phone grid north to the 'A' object and then hit 'set'.
